Rust version behind

My Rust deploys have suddenly stopped working this month.

I believe the reason to be the rust version got downgraded since, according to deploy logs it’s using 1.73.0

stable-x86_64-unknown-linux-gnu unchanged - rustc 1.73.0 (cc66ad468 2023-10-03)

When it’s documented to be using stable(1.76.0), and I don’t see anything about this change in Rust in recent changelogs

Do you have a $RUSTUP_TOOLCHAIN environment variable, or rust-toolchain file in your repository?

I have neither…
